First I must say that the extension M2 Easy Catalog Images is fantastic!! Thank you!
I just have one minor issue. Whenever I edit a category and save it in Magento 2, it removes the category thumbnail image. I then have to re-upload the image again but this time it creates an image_1 file. Over time I get image.jpg, image_1.jpg, image_2.jpg every time I edit a category. I can live with it, but it would be nice to not have to re-upload category images every time an edit is made.
